    Epidemiological Aspects of Hepatitis E Virus Infections between South Korea and Japan

    Abstract : Purpose: Hepatitis E outbreaks are a serious public health concern in the world. The pilots or air traffic controllers can be incapacitated by severe hepatitis symptoms. If the symptoms of acute hepatitis do not improve, it is not suitable for aviation duties. In this study, we compare of incidence status of hepatitis E virus (HEV) infections, and epidemic aspects between South Korea (from here on, ‘Korea’) and Japan. Methods: The raw data on confirmed of HEV infection cases were obtained from the National Notified Disease Surveillance System of Korea Diseases Control and Prevention Agency, the Ministry of Health and Welfare in Korea, and the National Epidemiological surveillance of Infectious Diseases surveillance system, administered by the National Institute of Infectious Diseases in Japan. Statistically significant differences between the epidemiological aspects and risk factors were determined using the Pearson’s chi-squared test or paired t-test. All data analyses were performed in Microsoft Excel 2010 (Microsoft, Redmond, WA, USA). Results: There were 191 cases of HEV infected cases with a prevalence rate (PR) of 0.37 per 100,000 populations of Korea in 2020. During the same year in Japan, there were 454 cases with a PR of 0.36. When compared, there is statistically none significantly differences. Moreover, both PR per 100,000 populations of HEV infections in habitat of two countries were compared, in the provinces (0.39) of Korea were much higher than that in capital city of Seoul (0.27; P

    항공 피로위험관리를 위한 생체수리적 모델 접근 방안

    Abstract : In the aviation sector, it is recommended to adopt an aviation safety management system (SMS) from international organizations (International Civil Aviation Organization, Federal Aviation Administration, etc.) and to apply a related system in each organization. Among them, fatigue management recommends fatigue risk management system (FRMS) operating as part of SMS proactive risk management. Advanced aviation organizations are developing and applying various related risk assessment techniques that consider characteristics in order to apply scientific and systematic FRMS. Among which the biomathematical fatigue model (BFM) are representative. The Bio-mathematical Model is designed to represent the level by converting it into a simple numerical score, taking into account various related factors for the measurement object. The BFM is tool to predict the level of fatigue of the crew based on scientific understanding of the factors that contribute to fatigue. The Biomathematical Model is used as a scientific approach that promotes the transition to a performance-based safety management. In this study, the recent trends and implications for the BFM developed and applied in the aviation field are to be reviewed. First, FRMS was considered within the SMS framework, then the characteristics and application methods of the BFM were examined, and finally, the direction of the development of the BFM was suggested.

    항공학과 학생들의 MBTI 성격 유형별 조직몰입 및 팀워크 역량 차이분석

    Abstract : Purpose: For students who have already decided on their career path by entering the aviation departments, this study aims to analyze organizational commitment and teamwork relationships using the Myers-Briggs Type Indicator (MBTI) personality type as a tool. Methods: In order to investigate the career choices of aviation workers according to MBTI personality types, a survey was conducted targeting enrolled in and graduating from the aviation departments, and organizational commitment and teawork were analyzed using SPSS WIN 21.0. Results: Sening, Feeling, and Perceiving were mainly found in students who chose cabin crew as their career, whereas students in department of flight crew and aviation maintenance showed high level in Instuition, Thinkg, and Juding. As a result of the analysis, the MBTI type for each career path of aviation students was mainly ENTP for flight crew students, ESFP for cabin crew students, and INTP for aviation maintenance students. Conclusion: Even if students make their choice based on advice, subjective and objective judgments in choosing a career path, there are cases in which the chosen job does not suit them. Therefore, it is hoped that various indicators such as the MBTI will be used to help studnes choose their career path.

    The Enhancing Error Management of Pilot and Line Operation Safety Audit

    Abstract : The human factors become the most important factor in aviation safety. In order to prevent accident, pilots should manage errors in the cockpit. International Civil Aviation Authority (ICAO) recommends airlines to implement line operation safety audit (LOSA) to identify the management of errors by pilots and understand real errors and the competencies. The LOSA may provide metrics of the prevalence of errors by each types and rate of trapping errors to management enhancing errors. Airlines may understand how crew respond and manage errors. The operator may enhance safety once they identify errors and train crew how they manage to reduce the most mismanagement errors. This study is to provide operators eight recommendations on how to enhance errors and LOSA understanding human errors collected through LOSA and enhancing the implementation of LOSA with guidance according to ICAO and Federal Aviation Administration.

    최근 6년간 일개 병원의 외국인 환자 현황과 코로나19의 영향

    Abstract : Purpose: As it becomes difficult to move between countries due to the spread of COVID-19, it can be expected that the number of foreign patients entering Korea for treatment will decrease significantly. The purpose of this study is to investigate the current status of hospitalization of foreign patients over the past 6 years and the impact of COVID-19. Methods: The sex, age, nationality, and histories of foreign patients who visited the International Medical Center from 2016 to 2021 were collected. A total of 25,569 subjects were analyzed. Results: For six years from 2016 to 2021, the number of foreign patients increased steadily before COVID-19 but decreased significantly after COVID-19. Overall, it was analyzed that the average annual growth rate of foreign patients from 2016 to 2019 was about 6%. However, due to the impact of COVID-19, the number of patients in 2020 decreased by about 57% compared to the previous year and by about 1% in 2021 compared to the previous year. Conclusion: It is believed that the decrease in foreign patients in a situation such as Corona 19 is due not only to the risk of infection, but also to the difficulty of moving between countries. In other words, it can be said that the driving force for the movement due to the medical skill gap still exists. Therefore, if this situation improves, it is judged that the phenomenon of moving abroad in search of medical care is inevitable.

    우주에서의 외과수술

    Abstract : For Mars exploration, spaceflight is advancing with the goal of sending manned spacecraft to Mars. Mars is 54.6 million kilometers away when it is closest to Earth. If a surgical emergency occurs during Mars exploration, it could take months or years to transport patients. Research estimates that an average of one surgical emergency will occur every 2.4 years during the Mars expedition for a crew of seven. Considering the astronomical cost of space travel and astronaut training, surgical treatment needs to be considered. There are various problems in performing surgery in space, but typically, physiological changes in the body due to microgravity, difficulty in performing surgery due to an unfamiliar environment, and difficulty in maintaining sterility can be considered. Also, since an experienced surgeon cannot ride on all spaceships, tele-surgery is required. As an alternative to overcome these problems, robot assisted minimal invasive surgery has been proposed. However, it is necessary to solve the signal delay caused by the longer distance. Other alternatives, such as the development of Robot technology, rapid transport due to trauma pod, and performing surgery while notifying the crew medical officer, have been suggested.
